Negative Pressure Wound Therapy With Instillation and Dwell Time Modifications for Lower Limb Wounds With the Waterfall Technique: A Case Series.

Background: Negative pressure wound therapy with instillation and dwell time (NPWTi-d) is an integrated system that combines conventional NPWT with an irrigation feature. Wound size and location of diabetic foot wounds may make NPWTi-d utilization difficult, commonly resulting in leakages and blockages.

Objective: This study evaluates the effectiveness of a novel waterfall technique, a modification of the usual bridging used during NPWTi-d application, to facilitate the channeling of instillation fluid into diabetic foot wounds with small entry points.

Negative Pressure Wound Therapy With Instillation and Dwell Time Used to Treat a Deep Foot Abscess With a Small Plantar Surface Incision.

Introduction: Deep soft tissue wounds have a significant volume of dead space that often delays healing. Negative pressure wound therapy with instillation and dwell time (NPWTi-d) used as an irrigation channel to manage deep cavity wounds with a tunneled opening has yet to be described to the authors' knowledge.

Case Report: The patient presented with pain and swelling of the left foot along with fever, elevated inflammatory markers, and signs of infection.
